Yes, the MPL and the GPL are not compatible.  But you don't have to
link them together.  Just use fork/exec to run gpg - this is perfectly
legal.  There is also a special interface to control gpg from another
program (see tools/shmtest.c).   A more convenient way would be to use
the PGG wrapper library,  this is also GPLed but maybe we can
convinmce Michael to make an exception for MPL.  I am very interested
to make Mozilla (or even Netscape) OpenPGP aware.
